DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Example methods, apparatus, and products for extracting and mining ofquote data across multiple languages in accordance with the presentinvention are described with reference to the accompanying drawings,beginning with FIG. 1. FIG. 1 sets forth a block diagram of automatedcomputing machinery comprising an example computer (152) useful inextracting and mining of quote data across multiple languages accordingto embodiments of the present invention. The computer (152) of FIG. 1includes at least one computer processor (156) or ‘CPU’ as well asrandom access memory (168) (‘RAM’) which is connected through a highspeed memory bus (166) and bus adapter (158) to processor (156) and toother components of the computer (152).

Stored in RAM (168) is a quote analysis module (212), a module ofcomputer program instructions improved for extracting and mining ofquote data across multiple languages according to embodiments of thepresent invention. The quote analysis module (212) is depicted as beinga single module but may include many modules of computer programinstructions.

The quote analysis module (212) of FIG. 1 may carry out extracting andmining of quote data across multiple languages according to embodimentsof the present invention by retrieving, from a plurality of quotesources, a plurality of commentary summarizations. Each quote source caninclude any entity that distributes content containing quotations fromone or more individuals or entities. Examples of quote sources caninclude a news agency that distributes printed news stories, a newsagency that delivers online news stories, a publisher that distributesmagazines, a company that gathers and distributes opinions fromregistered users, and many others. Quote sources may be accessible tothe quote analysis module (212), for example, via a news wire thataggregates news stories, through the use of a web crawler or similartechnology for searching online content posted by the quote sources,through the use of a technology that translates audio content containingquotations into a machine readable format, through the use of atechnology that translates printed content into a machine readableformat, and so on.

Each commentary summarization can include content that includesquotations from one or more individuals, quotations from a businessentity in the form of a press release, or quotations from otherentities. For example, a first commentary summarization can be generatedbased on a news article distributed by a news agency that includesquotations from one or more individuals as part of the news article.Similarly, a second commentary summarization can be generated based on atranscript from an interview conducted with a notable political figure.Each commentary summarization is embodied as a machine-readable datastructure. For example, the commentary summarization may be embodied asa structured document, such as an extensible markup language (‘XML’)document, that includes quotations from a commentator, content fromwhich the quotations was extracted (e.g., a news article), and so on.Such a structured document may also include metatdata identifying thesource of the content contained in the commentary summarization, thetime at which the content contained in the commentary summarization wasgenerated, an identification of the particular people that are quoted inthe content contained in the commentary summarization, an identificationof the general topic of the content contained in the commentarysummarization, and so on.

The plurality of commentary summarizations can include information in atleast two or more languages. For example, a first commentarysummarization can include a transcript of an interview conducted inEnglish, as well as quotations that were given in the English language.Likewise, a second commentary summarization can include a transcript ofan interview conducted in Spanish, as well as quotations that were givenin the Spanish language. In such a way, the quote analysis module (212)can retrieve a plurality of commentary summarizations in differentlanguages from a wide range of quote sources that operate in differentcountries and regions.

The quote analysis module (212) of FIG. 1 may further carry outextracting and mining of quote data across multiple languages accordingto embodiments of the present invention by identifying, within thecommentary summarizations, quote data. The quote data represents a quotefrom a commentator. Identifying quote data within the commentarysummarizations may be carried out, for example, by searching the contentfor indicators of a quotation such as quotation marks, phrases thatindicate a quotation (e.g., President Obama was quoted as saying . . .), and so on. In some embodiments, the commentary summarizations may beembodied as a structured document that includes tags for quotations. Forexample, a portion of the commentary summarizations may include thefollowing structure:

-   -   <quote commentator=“Franklin D. Roosevelt”>The only thing we        have to fear is fear itself</quote>

In such an example, the structure of the commentary summarizations maybe utilized to identify (216) quote data within the commentarysummarizations.

The quote analysis module (212) of FIG. 1 may further carry outextracting and mining of quote data across multiple languages accordingto embodiments of the present invention by creating, in dependence uponthe quote data, a quote tuple. The quote tuple includes informationassociated with quantifiable aspects of the quote data. The quote tuplecan include, for example, the identity of the commentator that aquotation is attributed to, the content of the quotation itself, thetime at which the quotation was made, and so on. Creating a quote tuplemay be carried out by extracting such information from the commentarysummarizations using natural language processing techniques and storingsuch information in the appropriate field, variable, or data structurewithin the quote tuple.

The quote analysis module (212) of FIG. 1 may further carry outextracting and mining of quote data across multiple languages accordingto embodiments of the present invention by storing, in a quote tuplerepository, the quote tuple. The quote tuple repository may be embodied,for example, as a database such that each quote tuple is an entry insuch a database. Identifying quote data, creating a quote tuple, andstoring the quote tuple in a quote tuple repository is carried out foreach commentary summarization. As such, upon carrying out the stepsdescribed above for a particular commentary summarization, the quoteanalysis module may determine whether there are additional commentarysummarizations to be processed.

The quote analysis module (212) of FIG. 1 may further carry outextracting and mining of quote data across multiple languages accordingto embodiments of the present invention by mining, for quote analysisinformation, the quote tuple repository. The quote analysis informationrepresents an assessment as to the content of the quotations. Forexample, the quote analysis information can include informationidentifying commentators that have been quoted on a particular topic,information identifying the historical quotations of a particularcommentator on a particular topic, information identifying whether acommentator has a positive or negative view on a particular topic basedon the commentator's quotations on the topic, and so on. Mining thequote tuple repository for quote analysis information may be carried outby searching the quote tuple repository for relevant entries and usingnatural language processing techniques to extract meaning from therelevant entries found in the quote tuple repository.

The quote analysis module (212) of FIG. 1 may further carry outextracting and mining of quote data across multiple languages accordingto embodiments of the present invention by presenting, to a user, thequote analysis information. Presenting the quote analysis information tothe user may be carried out, for example, through the use of a graphicaluser interface (GUI′) that is accessible by the user. In the examplemethod of FIG. 2, such a GUI may be presented to the user through a webbrowser on a desktop computer, through a special purpose GUI on a laptopcomputer, through an application on a mobile communications device, andso on.

Examples of communications adapters useful forextracting and mining of quote data across multiple languages accordingto embodiments of the present invention include modems for wired dial-upcommunications, Ethernet (IEEE 802.3) adapters for wired datacommunications network communications, and 802.11 adapters for wirelessdata communications network communications.

For further explanation, FIG. 2 sets forth a flow chart illustrating anexample method for extracting and mining of quote data across multiplelanguages according to embodiments of the present invention. The examplemethod of FIG. 2 is depicted as being carried out, at least in part, bya quote analysis module (212). In the example method of FIG. 2, thequote analysis module (212) may be embodied as a module of computerprogram instructions executing on computer hardware, such as a computerprocessor. The quote analysis module (212) is depicted as being a singlemodule but may include many modules of computer program instructions.

The example method of FIG. 2 includes retrieving (214), from a pluralityof quote sources (202, 204, 206), a plurality of commentarysummarizations (208, 210, 212). In the example method of FIG. 2, eachquote source (202, 204, 206) can include any entity that distributescontent containing quotations from one or more individuals or entities.Examples of quote sources (202, 204, 206) can include a news agency thatdistributes printed news stories, a news agency that delivers onlinenews stories, a publisher that distributes magazines, a company thatgathers and distributes opinions from registered users, and many others.Quote sources (202, 204, 206) may be accessible to the quote analysismodule (212), for example, via a news wire that aggregates news stories,through the use of a web crawler or similar technology for searchingonline content posted by the quote sources (202, 204, 206), through theuse of a technology that translates audio content containing quotationsinto a machine readable format, through the use of a technology thattranslates printed content into a machine readable format, and so on.

Each commentary summarization (208, 210, 212) of FIG. 2 can includecontent that includes quotations from one or more individuals,quotations from a business entity in the form of a press release, orquotations from other entities. For example, a first commentarysummarization (208) can be generated based on a news article distributedby a news agency that includes quotations from one or more individualsas part of the news article. Similarly, a second commentarysummarization (210) can be generated based on a transcript from aninterview conducted with a notable political figure. In the examplemethod of FIG. 2, each commentary summarization (208, 210, 212) isembodied as a data structure. For example, the commentary summarization(208, 210, 212) may be embodied as a structured document, such as an XMLdocument, that includes quotations from a commentator, content fromwhich the quotations was extracted (e.g., a news article), and so on.Such a structured document may also include metatdata identifying thesource of the content contained in the commentary summarization (208,210, 212), the time at which the content contained in the commentarysummarization (208, 210, 212) was generated, an identification of theparticular people that are quoted in the content contained in thecommentary summarization (208, 210, 212), an identification of thegeneral topic of the content contained in the commentary summarization(208, 210, 212), and so on. In the example method of FIG. 2, theplurality of commentary summarizations (208, 210, 212) includeinformation in at least two or more languages. For example, a firstcommentary summarization (208) can include a transcript of an interviewconducted in English, as well as quotations that were given in theEnglish language. Likewise, a second commentary summarization (210) caninclude a transcript of an interview conducted in Spanish, as well asquotations that were given in the Spanish language. In such a way, thequote analysis module (212) can retrieve (214) a plurality of commentarysummarizations (208, 210, 212) in different languages from a wide rangeof quote sources (202, 204, 206) that operate in different countries andregions.

The example method of FIG. 2 also includes identifying (216), within thecommentary summarizations (208, 210, 212), quote data. In the examplemethod of FIG. 2, the quote data represents a quote from a commentator.Identifying (216) quote data within the commentary summarizations (208,210, 212) may be carried out, for example, by searching the content forindicators of a quotation such as quotation marks, phrases that indicatea quotation (e.g., President Obama was quoted as saying . . . ), and soon. In some embodiments, the commentary summarizations (208, 210, 212)may be embodied as a structured document that includes tags forquotations. For example, a portion of the commentary summarizations(208, 210, 212) may include the following structure:

-   -   <quote commentator=“Franklin D. Roosevelt”>The only thing we        have to fear is fear itself</quote>

In such an example, the structure of the commentary summarizations (208,210, 212) may be utilized to identify (216) quote data within thecommentary summarizations (208, 210, 212).

The example method of FIG. 2 also includes creating (218), in dependenceupon the quote data, a quote tuple (220). In the example method of FIG.2, the quote tuple (220) includes information associated withquantifiable aspects of the quote data. The quote tuple (220) caninclude, for example, the identity of the commentator that a quotationis attributed to, the content of the quotation itself, the time at whichthe quotation was made, and so on. Creating (218) a quote tuple (220)may be carried out, for example, by extracting such information from thecommentary summarizations (208, 210, 212) using natural languageprocessing techniques and storing such information in the appropriatefield, variable, or data structure within the quote tuple (220).

The example method of FIG. 2 also includes storing (224), in a quotetuple repository (238), the quote tuple (220). In the example method ofFIG. 2, the quote tuple repository (238) may be embodied, for example,as a database such that each quote tuple (220) is an entry in such adatabase. In the example method of FIG. 2, identifying (216) quote data,creating (218) a quote tuple (220), and storing (224) the quote tuple(220) in a quote tuple repository (238) is carried out for eachcommentary summarization (208, 210, 212). As such, upon carrying out thesteps described above for a particular commentary summarization (208),the quote analysis module (212) may determine whether there areadditional commentary summarizations (210, 212) to be processed. In theexample method of FIG. 2, if there are additional commentarysummarizations (222) to process, execution of the method of FIG. 2returns to step 216. If there are no additional commentarysummarizations (226) to process, execution of the method of FIG. 2continues to step 228.

The example method of FIG. 2 also includes mining (228), for quoteanalysis information (232), the quote tuple repository (238). In theexample method of FIG. 2, the quote analysis information (232)represents an assessment as to the content of the quotations. Forexample, the quote analysis information (232) can include informationidentifying commentators that have been quoted on a particular topic,information identifying the historical quotations of a particularcommentator on a particular topic, information identifying whether acommentator has a positive or negative view on a particular topic basedon the commentator's quotations on the topic, and so on. In the examplemethod of FIG. 2, mining (228) the quote tuple repository (238) forquote analysis information (232) may be carried out by searching thequote tuple repository (238) for relevant entries and using naturallanguage processing techniques to extract meaning from the relevantentries found in the quote tuple repository (238).

The example method of FIG. 2 also includes presenting (230), to a user(236), the quote analysis information (232). In the example method ofFIG. 2, presenting (230) the quote analysis information (232) to theuser (236) may be carried out, for example, through the use of agraphical user interface (GUI′) (234) accessible by the user (236). Inthe example method of FIG. 2, such a GUI (234) may be presented to theuser (236) through a web browser on a desktop computer, through aspecial purpose GUI on a laptop computer, through an application on amobile communications device, and so on.

For further explanation, FIG. 3 sets forth a flow chart illustrating anadditional example method for extracting and mining of quote data acrossmultiple languages according to embodiments of the present invention.The example method of FIG. 3 is similar to the example method of FIG. 2,as it also includes retrieving (214) a plurality of commentarysummarizations (208, 210, 212), identifying (216) quote data, creating(218) a quote tuple (220), storing (224) the quote tuple (220) in aquote tuple repository (238), mining (228) the quote tuple repository(238) for quote analysis information (232), and presenting (230) thequote analysis information (232) to a user (236).

In the example method of FIG. 3, each quote tuple (220) includesinformation associated with an identity (302) of the commentator. Theinformation associated with an identity (302) of the commentator caninclude any identifier that identifies the commentator that made aparticular quote. The information associated with an identity (302) ofthe commentator can include, for example, the name of a person that madea quote, the username of a person that made a quote, the title (e.g.,President, Chief Executive Officer, Analyst) of a person that made aquote, the name of a business organization that issued a quote, and soon.

In the example method of FIG. 3, information associated with an identity(302) of the commentator can be extracted from the content thatcontained the quote. Consider an example in which a commentarysummarization (208) included textual content contained in a news articlefrom a news agency. In such an example, the quote analysis module (212)may be configured to search the text of the news article and identifyquotes contained therein, for example, by searching for indicators of aquote such as a quotation mark. Upon the discovery of a quotation, thequote analysis module (212) may be further configured to search the textsurrounding the quotation for key phrases (e.g., was quoted as stating,stated that, said) suggesting that a quote is contributable to aparticular person. In such a way, the quote analysis module (212) may beconfigured to extrapolate the identity of a commentator from the contentthat contained the quote. In alternative embodiments, the commentarysummarization (208) may be embodied as a structured document, such thatthe identity (302) of the commentator can be identified by examiningdata within predefined tags that contains the commentator's identity, byexamining predefined attributes within a tag that contains thecommentator's identity, and so on.

In the example method of FIG. 3, information associated with an identity(302) of the commentator can alternatively be extracted from contentrelated to the content that contained the quote. Consider an example inwhich a commentary summarization (208) included textual contentcontained in a news article from a news agency. In such an example, whenthe quote analysis module (212) cannot clearly identify the identity(302) of the commentator from the news article, the quote analysismodule (212) may be configured to search the text of related newsarticles to determine the identity (302) of the commentator. Forexample, the quote analysis module (212) may be configured to identify arelated news story from a different news agency and identify quotescontained therein by searching for indicators of a quote such as aquotation mark. Upon the discovery of a quotation in the related newsstory, the quote analysis module (212) may be further configured tocompare the content of the quotation contained in the original newsarticle to the content of the quotation contained in the related newsarticle, determine that the content of the quotation contained in theoriginal news article is related to the content of the quotationcontained in the related news article, and determine that thecommentator for each quote is identical. In such a way, the quoteanalysis module (212) may be configured to extrapolate the identity of acommentator from the related content that contained a related quote.

In the example method of FIG. 3, each quote tuple (220) also includesinformation (304) associated with a quote from the commentator. Theinformation (304) associated with a quote from the commentator mayinclude, for example, the text of the quote itself. In such an example,the information (304) associated with a quote from the commentator maybe extracted from the content that contained the quote. Consider anexample in which a commentary summarization (208) included textualcontent contained in a news article from a news agency. In such anexample, the quote analysis module (212) may be configured to search thetext of the news article and identify quotes contained therein, forexample, by searching for indicators of a quote such as a quotationmark. Upon the discovery of a quotation, the quote analysis module (212)may be further configured to extract the text contained within thequotation marks and designate such text as information (304) associatedwith a quote from the commentator. In alternative embodiments, thecommentary summarization (208) may be embodied as a structured document,such that the information (304) associated with a quote from thecommentator can be identified, for example, by examining data withinpredefined tags that contains the quotation.

In the example method of FIG. 3, each quote tuple (220) also includesinformation (306) associated with a timing of the quote. The information(306) associated with a timing of the quote can include, for example,the time the quote was made, the date a quote was made, a relative time(e.g., three weeks ago) that the quote was made, and so on. In such anexample, the information (306) associated with a timing of the quote canbe extracted from the content that contained the quote. Consider anexample in which a commentary summarization (208) included textualcontent contained in a news article from a news agency. In such anexample, the quote analysis module (212) may be configured to search thetext of the news article and identify dates contained therein. The quoteanalysis module (212) may be configured to search the text of the newsarticle and identify dates contained therein, for example, by searchingfor indicators of a quote such as a quotation mark and subsequentlysearching the surrounding text for phrases (e.g., last week, on March17^(th), and so on). In addition, the quote analysis module (212) may beconfigured to search the text of the news article for data that is inthe format of a date (e.g., ______) to identify the publication date ofthe article, which may be used as the date at which a quotation wasattributed to a commentator. In alternative embodiments, the commentarysummarization (208) may be embodied as a structured document, such thatthe information (306) associated with the timing of the quote can beidentified, for example, by examining data within predefined tags thatcontains date information, by examining predefined attributes within atag that contains date information, and so on.

In the example method of FIG. 3, each quote tuple (220) also includesinformation (308) associated with a context of the quote. In the examplemethod of FIG. 3, information (308) associated with a context of thequote may include, for example, an identification of one more topicsthat the quotation is directed to, an indication of whether thecommentator is making positive or negative comments on a particulartopic, and so on. In the example method of FIG. 3, identifying theinformation (308) associated with a context of the quote may be carriedout, for example, through the use of natural language processingtechniques and natural language understanding techniques for assigningmeaning by machines to human language input. In such an example, thequote analysis module (212) may be configured with, or otherwise haveaccess to, natural language understanding sub-modules for implementingnatural language understanding techniques. For example, the quoteanalysis module (212) may be configured with, or other otherwise haveaccess to, a lexicon of the language, a parser, grammar rules to breaksentences into internal representations, a semantic theory module toguide the comprehension of the component parts of human language input,and so on. In alternative embodiments, the commentary summarization(208) may be embodied as a structured document, such that theinformation (308) associated with a context of the quote can beidentified, for example, by examining data within predefined tags thatcontains context information, by examining predefined attributes withina tag that contains context information, and so on.

In the example method of FIG. 3, mining (228) the quote tuple repository(238) for quote analysis information (232) can include identifying (310)a particular topic of interest. As described above, each quote tuple(220) may include information (308) associated with a context of thequote that includes an identification of the topic that a quote isrelated to. In such an example, the identification of the topic that aquote is related to may be embodied as a numerical value that representsan index into a listing of predetermined topics, as a string value thatrepresents an index into a listing of predetermined topics, and so on.Identifying (310) a particular topic of interest may therefore becarried out by a user (236) entering a description of a topic, usingsuch a description of a topic to identify an index into a listing ofpredetermined topics, and identifying all quote tuples (220) in a quotetuple repository (238) that are associated with the identified indexinto a listing of predetermined topics. Consider an example in which thequote analysis module (212) maintains, or otherwise has access to, thefollowing listing of predetermined topics:

TABLE 1 Topics Table Topic Description Topic ID Chicago Bears Football 1Chicago Cubs Baseball 2 Chicago Restaurants 3 Chicago Hotels 4

The topics table described above includes a topic description and anidentifier of such a topic. In such an example, quote tuples (220)generated in response to a quotation related to Chicago Bears Footballmay be assigned a topic identifier value of ‘1’ in the information (308)associated with a context of the quote while quote tuples (220)generated in response to a quotation related to Chicago Cubs Baseballmay be assigned a topic identifier value of ‘2’ in the information (308)associated with a context of the quote. In order to identify (310) aparticular topic of interest, a user (236) may be prompted to enter adescription of a topic or be provided a list of available topics suchthat the topic identifier for the particular topic of interest can beidentified. In such an example, the quote tuple repository (238) couldsubsequently be searched for tuples that are related to the particulartopic of interest in order to retrieve quotations related to theparticular topic of interest.

In the example method of FIG. 3, mining (228) the quote tuple repository(238) for quote analysis information (232) can also include identifying(312) a commentator of interest. As described above, each quote tuple(220) may include information associated with an identity (302) of thecommentator that made a particular quote. In such an example, theidentity (302) of the commentator that made a particular quote may beembodied as a numerical value that represents an index into a listing ofpredetermined commentators, as a string value that represents an indexinto a listing of predetermined commentators, and so on. Identifying(312) a commentator of interest may therefore be carried out by a user(236) entering a name or other description of a commentator, using sucha description of a commentator to identify an index into a listing ofpredetermined commentators, and identifying all quote tuples (220) inthe quote tuple repository (238) that are associated with thecommentator of interest. Consider an example in which the quote analysismodule (212) maintains, or otherwise has access to, the followinglisting of predetermined commentators:

TABLE 2 Commentators Table Commentator Description Commentator IDChicago Tribune Newspaper 1 Hilary Clinton 2 Barack Obama 3 MichaelJordan 4

The commentators table described above includes a commentatordescription and an identifier for each commentator. In such an example,quote tuples (220) generated in response to quotations made by HilaryClinton may be assigned a commentator identifier value of ‘2’ in theidentity (302) of the commentator while quote tuples (220) generated inresponse to quotations made by Michael Jordan may be assigned acommentator identifier value of ‘4’ in the identity (302) of thecommentator. In order to identify (312) a commentator of interest, auser (236) may be prompted to enter a description of a commentator or beprovided a list of available commentators such that the commentatoridentifier for the particular commentator of interest can be identified.In such an example, the quote tuple repository (238) could subsequentlybe searched for tuples that are related to the commentator of interestin order to retrieve quotations made by the commentator of interest.

In the example method of FIG. 3, mining (228) the quote tuple repository(238) for quote analysis information (232) can also include determining(314), for the commentator of interest, the commentator's position onthe particular topic of interest. In the example method of FIG. 3, thecommentator's position on the particular topic of interest represents anopinion, assessment, or other view held by the commentator on theparticular topic of interest. For example, the commentator's positionmay include a commentator's evaluation that a stock is overpriced, alegislator's opinion that a particular piece of proposed legislationshould be passed, a commentator's evaluation that an act committed by acompany was unethical, and so on.

As described above, identifiers for both the commentator of interest andthe topic of interest can be retrieved. In such an example, determining(314) the position of the commentator of interest on the particulartopic of interest may be carried out by identifying all quote tuples(220) in the quote tuple repository (238) that are attributable to thecommentator of interest and are also related to the particular topic ofinterest. In such an example, determining (314) the commentator'sposition on the particular topic of interest may therefore be carriedout by applying natural language processing techniques and naturallanguage understanding techniques to determine whether a quotation ineach identified quote tuple (220) indicates that the commentator ofinterest is expressing a positive or negative opinion on the topic ofinterest. In such a way, the quote analysis module (212) may thereforedetermine whether a majority of the quotes made by the commentator ofinterest on the topic of interest are positive, negative, neutral, orrepresent some other opinion. In such an example, presenting (230) thequote analysis information (232) to a user (236) may therefore includepresenting the user (236) with a count of positive quotes made by thecommentator of interest on the topic of interest, presenting the user(236) with a count of negative quotes made by the commentator ofinterest on the topic of interest, presenting the user (236) with apercentage indicating what portion of quotes made by the commentator ofinterest on the topic of interest are positive or negative, and so on.

For further explanation, FIG. 4 sets forth a flow chart illustrating anadditional example method for extracting and mining of quote data acrossmultiple languages according to embodiments of the present invention.The example method of FIG. 4 is similar to the example method of FIG. 2,as it also includes retrieving (214) a plurality of commentarysummarizations (208, 210, 212), identifying (216) quote data, creating(218) a quote tuple (220), storing (224) the quote tuple (220) in aquote tuple repository (238), mining (228) the quote tuple repository(238) for quote analysis information (232), and presenting (230) thequote analysis information (232) to a user (236). In the example methodof FIG. 4, mining (228) the quote tuple repository (238) for quoteanalysis information (232) can include identifying (310) a particulartopic of interest. In the example method of FIG. 4, identifying (310) aparticular topic of interest may be carried out as described above withreference to FIG. 3.

In the example method of FIG. 4, mining (228) the quote tuple repository(238) for quote analysis information (232) can also include identifying(402) commentators qualified to comment on the particular topic ofinterest. In the example method of FIG. 4, identifying (402)commentators qualified to comment on the particular topic of interestmay be carried out, for example, by identifying commentators that mostfrequently comment on the particular topic of interest, by identifyingcommentators whose position (e.g., President of company A) indicates alevel of knowledge on the particular topic of interest (e.g., theperformance of company A), by identifying commentators that areaffiliated with trusted organizations, by a user (236) assigning a trustlevel to a particular commentator on the particular topic of interest,and so on. In such a way, identifications of commentators qualified tocomment on the particular topic of interest may be associated with anidentifier of the topic of interest in a table, database, or otherrepository that is maintained, or otherwise accessible by, the quoteanalysis module (212).

In the example method of FIG. 4, mining (228) the quote tuple repository(238) for quote analysis information (232) can also include determining(404), for each commentator qualified to comment on the particular topicof interest, the commentator's position on the particular topic ofinterest. As described above, identifiers for both the commentator ofinterest and the topic of interest can be retrieved. In such an example,determining (404) the position of each commentator qualified to commenton the particular topic of interest may be carried out by identifyingall quote tuples (220) in the quote tuple repository (238) that arerelated to the particular topic of interest and also attributable to thecommentator qualified to comment on the particular topic of interest. Insuch an example, determining (404) the position of each commentatorqualified to comment on the particular topic of interest may thereforebe carried out by applying natural language processing techniques andnatural language understanding techniques to determine whether aquotation in each identified quote tuple (220) indicates that thecommentator qualified to comment on the particular topic of interest isexpressing a positive or negative opinion on the topic of interest. Insuch a way, the quote analysis module (212) may therefore determinewhether a majority of the quotes on the particular topic of interestthat are made by each commentator qualified to comment on the particulartopic of interest are positive, negative, or neutral.

In the example method of FIG. 4, mining (228) the quote tuple repository(238) for quote analysis information (232) can also include determining(406), in dependence upon each commentator's position on the particulartopic of interest, an expert position on the particular topic ofinterest. In the example method of FIG. 4, the expert position on theparticular topic of interest represents the cumulative position of eachcommentator qualified to comment on the particular topic of interest. Insuch an example, determining (406) an expert position on the particulartopic of interest may therefore be carried out by applying an algorithmthat takes into account the position of each commentator qualified tocomment on the particular topic of interest. Such an algorithm may applyvarious weighting criteria such that the position of a first commentatorqualified to comment on the particular topic of interest is more heavilyweighted than a second commentator qualified to comment on theparticular topic of interest. Similarly, the algorithm may take intoaccount the extent to which each commentator qualified to comment on theparticular topic of interest is positive or negative, such that a highlynegative position by a first commentator qualified to comment on theparticular topic of interest is more heavily weighted than a slightlypositive position by a second commentator qualified to comment on theparticular topic of interest. In such an example, presenting (230) thequote analysis information (232) to a user (236) may therefore includepresenting the user (236) with a count of qualified commentators with apositive position on the topic of interest, presenting the user (236)with a count of qualified commentators with a negative position on thetopic of interest, presenting the user (236) with a weighted average ofthe position of all qualified commentators on the topic of interest, andso on.

For further explanation, FIG. 5 sets forth a flow chart illustrating anadditional example method for extracting and mining of quote data acrossmultiple languages according to embodiments of the present invention.The example method of FIG. 5 is similar to the example method of FIG. 2,as it also includes retrieving (214) a plurality of commentarysummarizations (208, 210, 212), identifying (216) quote data, creating(218) a quote tuple (220), storing (224) the quote tuple (220) in aquote tuple repository (238), mining (228) the quote tuple repository(238) for quote analysis information (232), and presenting (230) thequote analysis information (232) to a user (236). In the example methodof FIG. 5, mining (228) the quote tuple repository (238) for quoteanalysis information (232) can include identifying (310) a particulartopic of interest and identifying a commentator of interest (312) asdescribed above with reference to FIG. 3.

In the example method of FIG. 5, mining (228) the quote tuple repository(238) for quote analysis information (232) can also include detecting(502), for the commentator of interest, a change in the commentator'sposition on the particular topic of interest. In the example method ofFIG. 5, detecting a change in the commentator's position on theparticular topic of interest may be carried out, for example, byretaining information describing the commentator's position on theparticular topic of interest as evidenced by each quotation made by thecommentator of interest. In such a way, the quote analysis module (212)may be configured to examine a predetermined number of most recentquotations by the commentator of interest and determine whether thepredetermined number of most recent quotations by the commentator ofinterest represent a position that is similar to a position expressed byhistorical quotations of the commentator of interest. Likewise, thequote analysis module (212) may be configured to examine a predeterminednumber of most recent quotations by the commentator of interest todetermine which direction the commentator's position is trending on theparticular topic of interest.

In the example method of FIG. 5, mining (228) the quote tuple repository(238) for quote analysis information (232) can also include identifying(504) all commentators that that have issued a predetermined number ofquotations on the particular topic of interest. As described above, eachquote tuple (220) in the quote tuple repository (238) may include anidentifier of the commentator that made a particular quote and anidentifier of the topic of the particular quote. In such a way,identifying (504) all commentators that that have issued a predeterminednumber of quotations on the particular topic of interest may be carriedout by searching the quote tuple repository (238) for all entriesassociated with the identifier for the particular topic of interest. Insuch a way, the quote analysis module (212) may be configured todetermine how many entries in the quote tuple repository (238) areassociated with each commentator, such that commentators that that haveissued a predetermined number of quotations on the particular topic ofinterest may be identified (504). In such a way, a user (236) may bepresented with a list of active commentators that are issuing quotationson the particular topic of interest.

Readers will appreciate that the methods, apparatus, and productsdescribed above operate on a plurality of commentary summarizations thatinclude information—such as quotations—in at least two or morelanguages.
